Editing Your Videos

Mediasite's web-based video editor is a "non-linear video editing" tool. To understand what that means, think about the old film reels used in movie production before the digital era. When shooting a movie, editors would have to gather the many film reels used during production and unspool them onto a large desk. They would then cut up and splice together various bits from each reel to form one final reel, which would make up the final production. That process is called "editing," and that "linear" approach was eventually replicated digitally. Because producers could now jump around to any part of the reel (now known as "tracks") rather than having to start at the beginning and work toward the end, the process became known as "non-linear" editing.

If it helps, consider this analogy: a word processor such as Microsoft Word would be an example of a non-linear writing tool, since authors can jump around the any part of their work to make changes at any time. Contrast that writing experience with that of a typewriter, or even quill-and-ink, and you should begin to understand the concept behind a non-linear video editing tool.

An Overview of Mediasite's Web-based Video Editor

The Playhead

Understanding the playhead is key to understanding video editing. Think of the playhead in a video editing application as you would the cursor in a word processing application. Wherever the playhead is, is where you're working in that moment and what you are seeing in the preview windows.
 

What is in the "Mediasite Menu Bar"

At the top of the image above, "Mediasite Menu Bar" is annotated. Here is a deeper look at what lies behind each option, from left to right:

  • Projects: You can have more than one video editing project going at the same time. If you need to take a break from editing one presentation to work on another, you can switch between the two using the "Projects" tab.
  • Saved/Unsaved: Lets you know whether or not Mediasite has automatically saved your work.
  • Commit: When you click "commit," you are committing your changes to your project. In other words, you're saying "I'm done making changes and want to show this to people now." Clicking this will reveal three options: Commit to Current, Commit to New, and Commit to Existing.
    • Commit to Current will overwrite the current presentation and replace it with your edited version. Use this if you do not wish to retain the original presentation in any form.
    • Commit to New will walk you through creating a new presentation out of the existing one. If you're happy with your edits but want to preserve the original, use this option. A new presentation (and therefore a new link) will be generated.
    • Commit to Existing will allow you to export your edited presentation into another existing presentation. You may have created the blank presentation ahead of time in preparation for this step. In effect, this allows you to skip the creation of a new presentation when you use "Commit to New".
  • Undo: Reverses your last edit.
  • Redo: Reapplies your last edit.
  • Revision History: If you're unhappy with the last few edits you made, or want to revert back and restore the condition of your presentation from X days ago, this option allows you to do that.
  • Rerun Slide Detection: Unlike the video portion, your "slides" are not recorded; rather, they are captured. Mediasite uses an algorithm to determine when a slide has changed and needs to be captured during a live presentation. Use this option if you feel this capturing process didn't work properly for whatever reason.
  • Convert to Audio: Strips your presentation of any video and slides, leaving only the audio behind.
  • Video Source: Mediasite has the potential to "switch" between multiple sources of video while recording a live presentation. This feature is not active for Ross.
  • Help: Opens a "support" channel or a link to "documentation." You may find the documentation helpful, however for support it's best to start with the Ross Helpdesk instead.
  • Commit Jobs (located far right): Because "committing" an editing presentation (as described above) takes time, this shows a progress bar and estimated time to completion.
     

What the "Various Editing Tools" Do

Near the middle of the image above, "Various Editing Tools" is annotated. Each tool is explained below, going from left to right.

  • Out Time: Clicking and dragging between two points on the timeline will select that portion of the video (and any slides that go with it). Clicking Out Time, then, cuts out the selected part of the video.
  • Uncut Time: If you highlight a portion of previously cut or removed video, Uncut Time makes it visible again.
  • Insert Slides: Position the playhead at a point on the timeline where you wish to insert a new slide, and click this button to browse for the slide on your computer. Slides must be image files, and not PowerPoint files. (You can save PowerPoint slides as images from the Save As menu.)
  • Delete Slides: First, click a single slide or highlight a series of slides and use this button to remove them from the presentation.
  • Replace Slides: Click a slide, then click this button to browse your computer for the image you'd like to replace it with.
  • Edit Slide: Give a selected slide a name and description, if desired.
  • Cut Slides: Removes a selected slide but "copies" it to your computer's clipboard so that it can be "pasted" elsewhere in the timeline.
  • Copy Slides: Copies a selected slide so that it can be duplicated elsewhere in the timeline.
  • Paste Slides: Pastes a previously cut or copied slide so that it can be duplicated or inserted elsewhere in the timeline.
  • Insert Chapter: Position the playhead at a point along the timeline of your video in which you'd like to insert a chapter marker. Viewers can then use the chapter button to advance and move through your video.
     

For longer videos, use chapters

The "Insert Chapter" button is a really important feature. Your viewers will appreciate being able to move freely throughout your video.

For example, if you're recording a lecture that covers a series of related topics, you may say to your audience, "if you've already heard me talk about Topic Y at length, use the chapter button to skip ahead to Topic Z." That way, viewers aren't forced to guess and click ahead at various points as they try to determine where you switch topics. Inserting and naming a chapter marker for them lets them skip right to where they want, instantly.
